Granted, the quality of the video isn’t great, but you can still get a good sense of the speed that the Tesla Semi is capable of. Exactly how quickly the Tesla Semi sprinted off the line in the video isn’t known, but within just a few seconds it’s already moved several hundred feet and disappeared into the sunset while sounding otherworldly. Given that the test was done in a closed area with people and cars, it probably wasn’t reaching its potential either. This rapid acceleration is achieved with the help of four independent motors powered by a battery that will last 500 miles on a single charge. A cheaper model will also be available with a 300-mile range.
